Agricultural and Biosystems Engineering
Soybeans are routinely grown in the upper Midwest as a cash crop. However, late planting coupled with an early freeze can result in frost-damaged or “green beans.” Even after processing, the resulting soybean meal and soy oil are still green due to high chlorophyll concentrations. Since the consumer is reluctant to purchase green soy oil, frost-damaged soybeans (FDS) are of little use to the processing industry and often are docked at local elevators. However, when done properly, FDS can be marketed effectively through livestock. Frost-damaged soybeans, green beans, and immature soybeans are all synonymous terms and will be denoted by FDS in the rest of this article. Raw refers to non-heat treated soybeans.
